Rich Felker	91d5aa0657	fix microblaze syscall register clobbers the kernel entry point for syscalls on microblaze nominally saves and restores all registers, and testing on qemu always worked since qemu behaves this way too. however, the real kernel treats r3:r4 as a potential 64-bit return value from the syscall function, and copies both over top of the saved registers before returning to userspace. thus, we need to treat r4 as always-clobbered.	12 years ago
rofl0r	dbed392410	fixup general __syscall breakage introduced in x32 port the reordering of headers caused some risc archs to not see the __syscall declaration anymore. this caused build errors on mips with any compiler, and on arm and microblaze with clang. we now declare it locally just like the powerpc port does.	12 years ago
Rich Felker	ccc7b4c3a1	remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part.	13 years ago

Rich Felker	8c0a3d9e5c	microblaze port based on initial work by rdp, with heavy modifications. some features including threads are untested because qemu app-level emulation seems to be broken and I do not have a proper system image for testing.	14 years ago
